Referring irst to Figure l, there is shown the complete apparatus for forming headbands and applyino' the headbands to `back linings and to boolis.` The apparatus comprises a base surmounted hy oppositely dis posed supporting standards 1,.sho\vn partly broken away, having extendedhorizontal top sections 2 formed integral therewith. A

frame 3 is seated in an indentation formed in the horizontal top section 2. Brackets l are mounted on the extension 2 formed onthe` supporting standards 1 hybolts 5.

The frame 3 is formed of oppositely dis-` posedlsections havingiintegral bushings de-` signed to receive a shaft 6. A. driving gear 7, having a silent ratchet 8 formed integral tliereivitlnas shovvn in Figure 7, is keyed to the shaft 6 by a spline 9. Apinion 10 `is loosay mounted on the shaft 6, formed With a cap 11 adapted to fit over the ratchet 8 and bc seated against the face of the driving gear 7. y

A plurality of ivedging rollers 12 are`seated in notches having tapered seats in the face of the ratchet 8. The rollers12 are provided with pushers 13 seated in apertures in the Walls oi the notches and held hy spiral springs 14:.

(ill

n latch 29. One end of the The cap 11 formed on the against the rollers 12 when and advances the ratchet 8 and the driving gear 7. `When rotated counter clockwise the rollers 12 are released and the cap operated without movement of the ratchet.

A roller 14, as shown in Figure is mounted on the shaft 6 adapted to rotate with the ratchet 8. A housing cap 15 is iiXedly mounted over the pinion l() and is formed with an integral communicating channel guide casing 16 on one side to receive a rack 17, adapted to operate the pinion 19independently of the shaft 6 and the ratchet 8.

The rack 17, as shown in Fig. 1, is entended to form a connecting rod 1 having a terminal collared bushing 19. A pin 21 is seat' ed in the bushing 19 and is operable in a slet 22 formed in one end of an operating lever 23. The other end of the operating lever 23 is mounted on a shaft 25. A bell crank lever 26 formed with the collated bushing 24 is also mounted on the shaft 25.

A pin 28 is seated in an apertured extension 27 fo-rmed on one side of the operating lever 23, and acts as a fulcrum for a. coupling coupling latch 29 engages the heel of the bell crank lever 26, and the other end is held by a shaft 31 seated in one end of a trip lever 32, mounted on the framecl by a pin 33.

The coupling latch 29 is held in engagement with the trip lever 32 by a tension spring 34 having one end secured in aperture 35 in the lever 23, and the other end attached to a lug 36 seated in the top of the coupling latch 29. rlhe bell crank lever 26 is provided with an aperture 37 designed to receive a tension spring 38, to retain the lever against a suitable operating mechanism not shown.

One end of a red 39 is attached to the trip lever 32 by a pin 31, and the rod is pivoted at its other end to an oscillating disk 41. One end of a link 42 is attached to the disk 41 and the other end pivoted to the arm 43 of a trip lever, its other arm 44 being adapted to engage a back roller 45 constituting part of a book clamp 47 traveling along the track 46.

If the machine is operated without a book in the clamp 47, the clamp will close and move leftward the roller 45, causing the roller to push the trip arm 44 back, and move the link 42 out and the trip rod 39 up. The upward movement of the trip rod 39 will lift the coupling latch 29 and disengage the mechanism from the heel 4of the bell crank lever 26. This disconnects the operating lever 23 and the operation of the ratchet 17 is prevented.

|The rack 17, operating' the pinion 10, intermittently advances the feed roller 14, retraction being prevented by the ball ratchet. A gear 48 is mounted on a shaft 49 journaled in the frame 3. The intermediate gear 51 is en,-

pinion 1G presses rotated clockwise gaged with a slitter operating gear 53 aiixed to a shaft 54 mounted for rotative movement in the frame 3, and engages an adjacent slitter operating gear 55, mounted on a shaft 56 in a similar manner.

The slitter gearY 53 meshes with an intermediate gear 57 carried by a shaft 58 and engaging a glue'roller operating gear 59, mounted on a shaft 61. The teeth on the gea-r 59 mesh with teeth .on a glue transfer roller operating gear 62 keyed on a shaft 63.

The feed roller 14, operated by the ratchet 8 and the pinion 10, is adapted to engage a roller 64, as shown in Fig. 2. The roller 64 is mounted on the shaft 49 and operated by the gear 48. The gear 48 engaging the intermediate gear 51 mounted on the shaft 52 operates the gear 53, mounted on the shaft 54 and a slitter roller 65 also mounted on the shaft 54. The gear 53, operating the gear 55, operates an adjacent slitter roller 66, mounted on the shaft 56. The gear 53 on the slitter roller shaft 54 engaging the intermediate gear 57 mounted on the shaft 58, meshes with the gear 59 mounted on the shaft 6l. rlhere is also mounted on the shaft 61 a roller 67 rlhe gear 59 operating the roller 67 engages the gear 62 mounted on the shaft 63. The roller 68 is keyed on the shaft 63 adJacent the roller 67 mounted on the shaft 61.

The frame 3, as shown in Figures 1 and 2, is formed with an integral seat 69 having seated thereon a pan 71. A bracket 70 having an integral bushing 72 adapted to receive a sha-ft 73 is mounted on the pan 71. A plurality of Scrapers 74 are fixed on the shaft 73 by collars 75 having integral supporting arms 76 formed therewith, as shown in Figs. 2 and 6. The collars are positioned on the shaft 73 by set screws 77. AThe Scrapers 74 contact with the rollers 68. These rollers are provided with integral collars 78 mounted on the shaft 63 and positioned by set screws 79.

The shaft 61 is journaled in the bracket 70, which is also provided withk split bearings 83 and 84 on each end secured to the middle of the bracket by bolts 82. The bearings 83 and 84 act as bushings for the shaft 63 and the shaft 73.

The shaft 6 supporting the feed roller 14 is journaled in the frame 3 and held by a split bearing cover 85 held by bolts 86.

A plurality of collars 87 are mounted on the shafts 54 and 56 and held thereon by set screws 88, as shown in Fig. V3. The collars 87 are provided with annular faces 89 having peripherial knife edges 91. The faces are secured on the collars by screws 92. The adjacent peripheral Vknife edges 91 are aligned to act as slitters for the back lining web, and the positioning of the collars on the. shaft determine the reduced width to which the web is trimmed to suit the book to be lined.

The extension 2 on the frame 1, as shown 11s-emes gral collars 99 formed in the frame 3. The` material is then threaded through the slitter shafts 54 and 56 and between the peripherial knife edges 91 so that it may be trimmed to' any desired Width. It then passes back around the roller 64 and up over the feed roller 14, and thence on to a feed table 101 formed integral with the frame 3.

The material is held on the feed roller by tractor pulleys 102, mounted on an axle 103. The axle 103 is seated in one end of arms 104 having an axle 105 seated in collared bushings 106 formed on the other end. The` axle 105 is mounted in bearings formed onthc frame 3. The set screws 107 are fixed in the collars 106 to position the arms 104 on the shaft 105. i

For severing successive sections of back lining with headband attached a knife blade 108 is mounted on the frame 3 above the feed table 101. The knife blade is provided with a pressure line 109 communicating with nozi Zles 111 formed in the blade.. The pressure line is fed from a flexible conduit 112 'fixed to the line 109 by a collar 113 leading from any suitable source of pressure.

A lever 114 is keyed on the shaft 25, as

shown in Fig. 1 andpivoted at the other end to a link 115 through a pin 115. The link 115 is pivoted to a knife table 116 by a pin 117` The knife table 116 is adapted to reciprocate in a channel 118 formed in the frame 3 and in alignment with the path of the book clamp 47. On the top of the knife table 116 is mounted .a backing table 119, preferably flexibly constructed, adapted to receive the material 96 fed under the knife blade 108.

The bell crank lever 26 oscillates the shaft 25, and jointly operates the lever 114 and the lever 23. reciprocating the knife table 116 and oscillating the pinion 10, thus alternate ly advancing the material under the knife blade 108 and reciprocating the knife table 116 and cutting the material 96 at the point of discharge under the knife blade. The ma` terial awaiting discharge is held on the feeding table 101 by air pressure through the conduit 109 and nozzles 111. The knife 103 is secured on the frame 3 by a stanchion 121 secured thereto by bolts 122. A link 123 is mounted in the end thereof, having the other end affixed in the knife 108 and adjusted by lock nuts 124 and 125 to adiust the position of the knife.

The frame 3 is formed with an integral, bushing 126 adapted to receive a shaft 127 having mounted thereon a head band guide roller 1281` as shown in Figure 2. There is also formed on the frame 3 an integral bushing 129 designed to receive an axle 131 having mounted thereon a head band guide roller 132 adapted to cooperate With the feed roller 14. Headband stripe 133 are introduced in the feed mechanism over the guide roller 128 and supplied with adhesive by contact with the glue transfer roller 68; They then pass over the guide roller 132 and are applied to the edges of the back lining 96 by contact- With the feed roller 14 carrying the back lining.

A headband forming mechanism is mounted on caca carrier bracket 4 secured to the extension 2, each adapted to refold tape material progressively into a headband strip and insert a cord in the fold to forni a bead. The bracket 4 is provided on the upper end With a plurality of integral seats 134, having seated therein pins 135. A plurality of supporting disks 136 are mounted on the pins and are designed to act as seats for spools of cord 137. There are also formed on the bracket 4- a plurality of integral seats 138 adapted to receive angle rods 139, having eyelets 141 formed on their end. Collars 142 are secured on the rods 135 having casings adapted to receive guide rods 143.

flhecords 137 are threaded through the eyelets 141, and carried over the guide rods 143 to rollers 144 mounted on a shaft 145. The shaft 145 is `seated in bushings 146, formed integral with the brackets 4. i

Extensions 147 are formed integral with brackets 4 or attached thereto having` provided on their endsintegral bushings 148, adapted to receive a shaft 149. The shaft 149 supports a reel 151 on which is Wound tape material 152.

The tape passes over a roller 153 mounted .in bushings 154 formed integral with the brackets 4 and a. roller 155 mounted in bushings 156, also formed integral with the brackets 4. The tape is then threaded over a, roller 157 mounted on a shaft 156 seated in integral bushings 159. The roller 157 depends into a pan 161, mounted on a frame 162, secured to the brackets 4. The tape then passes over a roller 163 mounted on a shaft 164, journaled in integral bushings 165, formed on the brackets 4. i

The cords on the rollers 144 are designed to pass over the rollers 163 and be superimposed on the tape 152, also on the rollers 163 having adhesive faces applied by the roller 157. The tape and cords pass from the rollers 163 to forming devices or chutes 1.66, mounted. on shafts 167'.Y journaledv in bushings 168 formed integral with the brackets 4.

Each forming chute 166, as shown in Figs. 9` and 10,'is formed with flanged guide Walls 169 and a pin 1.71 is attached by a bolt 172 adjacent thecenter. An additional pin 173 is mounted on the other side of the chute by a bolt. 17 4. A pin 17 3 is provided with an arm 175 having formed on the end a hollow cap 176, in which is seated a spiral spring 177, projecting against one side Wall 169. The cap 176 adjacent to the center of the chute presses against the pin 171 by the action of the spring 177. The tape 152 passes over the roller 163 with the cord 137, and is folded over the cord in passing between the pin 171 and the cap 176, to form headbands 133 entering the backing appara-tus over the roller 128.

The operation of this invention may be as follows. The back lining web 96 on the supply spool 95 is introduced on the roller 98 and passed between the slitter shafts 54 and 56 as shown in Figs. 2 and 3. rllhe plates 89 having peripherial knife edges may be adjusted longitudinally on the shaft to trim the paper web to any desired reduced Width, or paper of the correct Width to suit. the books may be introduced, and 'the knife dispensed with. The paper is then passed over the roller 64 and back over the feed roller 14. It is deemed desirable to form the roller With a knurled surface to afford a firmer grip on the stock.

One face of the headband supply tapes 152 on the reels 151 may be previously treated to carry a suitable dry adhesive substance. The gummed surfaces are moistened and rendered adhesive by passage over the rollers 157, depending in the pan 161, filled with Water or any other desirable moistener. If so desired ungummed supply tapes may be employed and the pan 161 lilled with an adhesive substance applied directly to the tapes by the rollers 157.

The untreated faces of the tapes are then passed over the rollers 163. The cords 137 on the, spools 135 are threaded through tbe eyelets 141 on 'the end of the angle rods 139, over the angle guides 143 and over the rollers 144.

The cords are progressively superimposed on the adhesive faces of the tapes on the rollers 163 and the tape and cords` passed down in the forming or folding devices or chutes 166. The tape is folded over the cord by being passed between the pin 171 and cap 176, as shown in Figs. S and 9, the tape thus progressively formed into headband strip and the cord forming the bead.

The headbands 133 are advanced over the rollers 12S and over the rollers 62. The rollers 62 contact With the rollers 59, depended in the pan 71, filled With glue or any other suitable adhesive. The glue is transferred from the rollers 59 to the rollers 62 and an even film on the rollers maintained by the Scrapers 74 as shown in Fig. 6, this film being applied upon one exposed side of the headband strip.

The headbands are then passed over the rollers 132 and thereby applied upon theedges of the paper web on the roller 14, from Which the assembled Web and headbands pass under the knife blade108. The paper vvith-y the headbands attached is held on the feed roller 14 by the tractor pulleys 102 and on the feed table 121 by air pressure introduced thr-ough the line 109 and down the conduits 111, as shown in Fig. 2.

A section of the lining is severed upon the table 119 by the rise of the applier carriage 116 and each severed headbanded lining section is applied to the back of the book, which has previously had a layer of Wet adhesive applied to it.

If no book is in the clamp 47, the trip lever 44 operating through the parts 42 vand 41 will lift the latch 32 and disengage the lever 23 from the operating bell crank 26 and so prevent the feeding of the lining to the empty clamp. y
